Vehicle Manufacturing Patents: Top Companies & Filing Trends 2026
- Concentrated at the top. The top 5 assignees together account for 54.3% of all 105 records in scope, and the top 10 for 74.3% — a small group holds most of the claim space.
- Filing has cooled sharply. From 2021 to 2024, filings by the leading assignees fell 100%, with the field's peak year (13 records) already behind it in 2019.
- Alloys and wet separation rival vehicle-structure claims. C22C alloy claims (16.2%) and B03B wet-separation claims (13.3%) sit close behind B62D motor-vehicle claims (18.1%), showing recycling-adjacent chemistry is as contested as vehicle structure itself.
Filing growth compares 2021 (7 records) with 2024 (0) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 105 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks patent activity where vehicle manufacturing and vehicle recycling intersect with process-level claims — process temperature, tool geometry, material feed, dimensional tolerance, material separation and recovery yield. That intersection is narrower than automotive patenting broadly: it captures how vehicles are built and how they are taken apart and recovered, not general vehicle electronics or software.
The 105 records in scope span 2015 through the current data cut-off, filed across six receiving offices led by the United States, with Europe and the WIPO PCT route also carrying meaningful volume. Publication lags filing by roughly 18 months, so the most recent one to two years understate true filing activity.

Filing trend and technology composition
Two views of the same 105 records: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
Filing trend: a clear peak, then a pullback
Filings rose from 4 in 2017 to a peak of 13 in 2019, then declined; by the last complete year in this trend, 2021's 7 filings among the leading assignees had fallen to 0 by 2024, a 100% drop. Because publication lags filing by about 18 months, 2025 and 2026 figures are still filling in and should not be read as confirmation the field has gone quiet.
Technology composition: vehicle structure leads, but not by much
B62D (motor vehicles & steering) tops the field at 18.1% of the 105 records, with C22C (alloys) at 16.2% and B03B (wet separation of solids) at 13.3% close behind. B60R, B29C and B32B each sit near or above 10%, and A61K and B21D round out the list — since records can carry multiple IPC classes, these shares add to more than 100% and should be read individually against the 105-record base, not summed.
Shares are the percentage of the 105 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

System and Method for Customizing Vehicle Tires on Demand at Point-of-Sale
Methods and systems for on demand, customized manufacture of vehicle tires at a point-of-sale are disclosed. At a point-of-sale, tire casings and tire treads that have been manufactured separately to enhance certain performance characteristics are assembled to provide a final customized tire.Filed by Bridgestone Americas Tire Operations, this record illustrates how manufacturing-process claims in this space reach past the vehicle itself into point-of-sale assembly — a boundary worth checking before assuming a claim only covers factory-floor process steps.

Three findings a reader would not get from browsing individual patents one at a time.
A small group controls most of the claim space
With the top 5 assignees alone covering 54.3% of all records in scope, new entrants are filing into a field where a handful of players already hold most of the established ground, particularly around vehicle structure and alloy composition.
Recent activity has fallen off sharply
The leading assignees' filing volume dropped to zero by 2024 from 7 in 2021. That decline predates the publication lag window, so it reflects a real pullback in new filings by the field's biggest players rather than a reporting artifact.
Alloy and separation claims rival vehicle-structure claims
Motor-vehicle structural claims (B62D) lead only narrowly over alloy claims (C22C) and wet-separation claims (B03B). Recovery and materials-processing technology is nearly as contested as the vehicle build itself, which matters for anyone assuming this is purely an automotive-assembly field.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to vehicle manufacturing & recycling patent landscape, with the prior art for and against each one.
Who is filing, and who has stopped
The ranked leaders span materials producers, recyclers and automakers rather than a single industry segment, and several have gone quiet in the most recent tracked year.
The top filer outpaces the field by a wide margin
The leading assignee's 14 records compare with 7 at fifth place and 4 at tenth — a steep drop-off that marks this as a field with one clear leader rather than several evenly matched competitors.
Multiple top filers show no recent activity
Several of the assignees near the top of the ranking, including materials and recycling specialists, recorded zero filings in the latest tracked year — consistent with the field-wide pullback, though the 18-month publication lag means some of this may still fill in.
Co-filing is limited and concentrated around one firm
Only eight co-assignee pairs appear in the dataset, and the strongest of them all involve the same aluminum materials producer paired with individual inventors — suggesting most other filers in this space are working, and filing, independently.

| SABIC Global Technologies B.V. | 0 | -100% |
| SA RECYCLING LLC | 0 | — |
| Divergent Technologies, Inc. | 0 | -100% |

Where to take this analysis
The dataset points to a field with a settled top tier and a cooling filing rate — the open questions are about where the remaining room to file actually sits.
Map the white space against the leader's portfolio
Before filing near B62D or C22C claims, check which sub-branches the top-ranked assignee has not yet covered rather than assuming the whole class is closed.
Explore white space in EurekaWatch for a filing rebound in the lag window
Because 2025–2026 filings are still publishing, re-check momentum by assignee again once the lag window closes rather than treating the 2024 low as final.
Track filing trends in EurekaLook past the vehicle-assembly framing
Wet-separation and alloy claims carry nearly as much weight as vehicle-structure claims, so a search strategy built only around automotive assembly terms will miss a meaningful share of relevant prior art.

One assignee leads the ranked field with 14 records, well ahead of the fifth-placed firm at 7 and the tenth-placed firm at 4. The top 5 assignees together hold 54.3% of all 105 records in scope, and the top 10 hold 74.3%, so filing activity is concentrated rather than evenly spread across the 38 companies in the ranking. Anyone assessing freedom to operate here should focus first on the handful of firms at the top rather than the long tail.
Filing peaked at 13 records in 2019 and has declined since; among the leading assignees, filings dropped from 7 in 2021 to 0 in 2024, a 100% fall over that span. That said, publication typically lags filing by around 18 months, so the 2025–2026 figures are still incomplete and should not be read as final confirmation of a shrinking field. A clearer picture will emerge once the lag window closes.
Motor-vehicle structural claims (IPC class B62D) lead at 18.1% of the 105 records in scope, followed closely by alloy claims (C22C) at 16.2% and wet separation of solids (B03B) at 13.3%. Because a single record can carry multiple IPC classes, these percentages are each measured against the full 105-record base rather than against each other, and they add to more than 100% in total. The near-parity between structural and materials/separation classes suggests recycling-adjacent chemistry is as actively claimed as vehicle assembly itself.
The evidence points to under-claimed ground in dimensional-tolerance control for recycled feedstock, material-separation yield in mixed-alloy scrap, and tool-geometry claims for multi-material joining — areas that sit adjacent to the dense B62D and C22C classes but carry comparatively fewer records. A first claim there would typically combine a specific process parameter, such as a tolerance range or separation yield target, with a named material system rather than claiming the process broadly. Checking the leading assignee's existing coverage before filing is a sensible first step given how concentrated the top of the ranking already is.
This Bridgestone Americas Tire Operations filing describes on-demand, point-of-sale assembly of tire casings and treads manufactured separately for distinct performance characteristics. It is notable less for citation volume and more for scope: it extends manufacturing-process claims beyond the factory floor into point-of-sale assembly, which is a boundary worth checking for anyone assuming process claims in this field stop at the plant gate. It should be read alongside the more heavily cited older records in the dataset, which concern manufacturing methods and extruded structural components rather than point-of-sale customization.
